roller rockers vs. standard rockers

[T-Punk]

Hey guys, just wanting to know how much more efficient the rollers are over some higher ratio standards. I have been trying to decide if i want to spend the extra money on the 1.9 ratio rollers or get the I-WIN 1.9 ratio non roller rockers. Would the only advantage with rollers be the ability to raise my rev limiter? The most i would raise it too would be 6000rpm so i dont think my app really requires the rollers. please help me out. I'm leaning towards the rollers but if its not really nessasary then i dont want to spend the extra money.

roller rockers reduce friction on the tip of the spring retainer. it might get you a little more efficient valvetrain, less wear, and a tiny bit more power. if ur trying to eek out every ounce of power out of the motor, go for the roller rockers.

Not worth it IMO. Neither are the 1.9 rockers...
The only difference is the roller tip, our rockers are quite nice stock.

It's prabobly best when making post about rockers to include your preference yea or nae for aftermarket cam to get more precise responses. Of course cam guys don't like the high ratio rockers, they have put in cams. The two don't go together. It realy just matters that if you can afford the price for either cam swap or high ratio rockers what your utimate goal for the engine is. The rockers are pricey HP to dollars. They work great with FI though, add some top end power on their own...even more with good aftermarket exhaust and unrestricted intake.
The non roller rockers you are refereing to are re-manufactured. You should probably get LS6 (medium load springs) at the same time. Possibly even aftermarket pushrods. By the time you buy a valve spring compressor...gets kinda pricey...so might as well get the rollers, they are aluminum as well, (less mass). If you are interested check our for sale forum. You see rockers there periodicaly when people decide they want more and go for a cam swap.
I like my set up. I have plans for forced induction and exhaust. The rockers will compliment that system well.

As far as price....I am not sure what all you have done to your car so far...but you would probaly feel more SOTP from say going to 3.42 gears rather 3.08 for the money...

Oh,...was not dissin AZ3.8 talking about cam swaps. That's just how things go with rockers vs. cam.
I can't talk much, though...check out his 1/4 mile time. He is doing something right.

They definately add power to a non cammed car.
They definately cost more than a cam.
Roller tip is definately better than not.
Our stock rockers have a roller style fulcrum. They are VERY good for stock rockers. They are aluminum also.
Roller tipped, 1.9 ratio is definately better, but is it worth the money? Thats where I doubt them.

I say install a cam. If you have a 3 day weekend, you can do it then. This is coming from someone who was in the same boat, but I decided to do the cam. Best mod I have done, hands down. Even if the sound was the only gain.

brapada, brapada, brapada, brapada, brapada,...oh, yea, that sound would be sweet.

Interesting...I did not realize our stock rockers are aluminum. So you would only gain the advantage of a roller tip for less friction. That is unless you choose the higher ratio for some extra lift.

FYI LS6 springs are in summit racing cat. for around less than 7$ a piece. Unless they are the wrong type?

im going turbo so a big cam is out of the question. this is why i was asking about rockers. so in this case what is the recomendation.

[AZ3.8Camaro]

Turbo cam is still leaps and bounds better than rockers. Its all about VALVE TIMING...

[grayman]

You could always wait until after the turbo instal. I mean, that should only take you about 2 or 3 hours...:)
You might have a better idea of how much more/what you need as far as valvetrain.

I need to find a magnet. My stock rockers are off. I don't think they are aluminum. Pressed steel i think. BRB.

Not aluminum. Pressed/formed steel.
buy going to aluminum rockers you reduce valvetrain enertial mass by about the weight of one piston.
DEFINATLY suggest high ratio rockers if you are going to change to aluminum rollers anyway...unless you plan on a cam...then go from there.

[AZ3.8Camaro]

They look aluminum to me... Take a looksie...

[grayman]

Steel. you cant get the strength required for someting like 6000 rpm rockers from thin aluminum like that anyway. they are ferous. magnet test.

The stock (and aftermarket) rocker pedastals are aluminum, though.

[RedFrk13]

I am almost positive they are steel. But I agree with AZ3.8Camaro in that I dont see a huge advantage with aluminum roller rockers. I dont think you would notice a difference from reworked 1.9s and aluminum roller 1.9s. Our stock rockers have the roller fulcrum which a great design for stock rockers and takes most of the weight of the rocker out of the picture.

Then again, the price of roller rockers are dropping and almost down to the price of reworked rockers.

Have you guys felt how heavy the stock Rockers are compared to the 1.8 SLP rockers. It's crazy. I love my SLP rockers. :D
